Shoe cushion for safety shoes

ABSTRACT

A shoe cushion for safety shoes includes a plurality of combination pieces pivotally connected with each other. Each of the combination pieces has a first side formed with a pivot shaft and a second side formed with a pivot groove. The pivot shaft of a first combination piece is inserted into and pivotally mounted in the pivot groove of an adjacent second combination piece. Thus, the combination pieces can be pivoted relative to each other so that the shape of the shoe cushion is changed freely so as to conform to the profile of the shoe sole of the shoe body and the profile of the user&#39;s one foot, thereby providing a comfortable sensation to the user wearing the shoe.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a shoe cushion, and more particularly to a shoe cushion for safety shoes.

2. Description of the Related Art

A conventional shoe cushion 20 in accordance with the prior art shown in FIG. 1 is used for one of a pair of safety shoes comprising a shoe body 10 and a shoe sole 15. The shoe cushion 20 is mounted on the top face of the shoe sole 15 of the shoe body 10. The shoe cushion 20 is made of hard metallic material to provide a protection effect to a user, thereby preventing the user's one foot from being hurt by a sharp object, such as a nail or the like. However, the shape of the shoe cushion 20 is fixed and cannot be changed to correspond to the profile of the shoe sole of the shoe body and the profile of a user's one foot, thereby easily causing an uncomfortable sensation to the user when wearing the shoe.

SUMMARY OF THE INVENTION

The present invention is to mitigate and/or obviate the disadvantage of the conventional shoe cushion.

The primary objective of the present invention is to provide a shoe cushion that has excellent mobility and provides a comfortable sensation to the user.

Another objective of the present invention is to provide a shoe cushion, wherein the combination pieces can be pivoted relative to each other so that the shape of the shoe cushion is changed freely so as to conform to the profile of the shoe sole of the shoe body and the profile of the user's one foot, thereby providing a comfortable sensation to the user wearing the shoe.

A further objective of the present invention is to provide a shoe cushion, wherein the shape of the shoe cushion is changed freely in one-dimensional or two-dimensional direction, so that the shoe cushion is bent freely to facilitate motion of the user's one foot.

In accordance with the present invention, there is provided a shoe cushion, comprising a plurality of combination pieces pivotally connected with each other, wherein each of the combination pieces has a first side formed with a pivot shaft and a second side formed with a pivot groove.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 2-6, a shoe cushion 60 in accordance with the preferred embodiment of the present invention is used for one of a pair of safety shoes comprising a shoe body 50 and a shoe sole 55. The shoe cushion 60 is mounted on a top face of the shoe sole 55 of the shoe body 50. The shoe cushion 60 is made of hard metallic material to provide a protection effect to a user, thereby preventing the user's one foot from being hurt by a sharp object, such as a nail or the like.

In the preferred embodiment of the present invention, the shoe cushion 60 comprises a plurality of combination pieces 70 pivotally connected with each other. The combination pieces 70 are juxtaposed to each other and arranged in a transverse manner. Each of the combination pieces 70 has a first side formed with a substantially convex pivot shaft 76 and a second side formed with a substantially concave pivot groove 78. The pivot shaft 76 of each of the combination pieces 70 has a periphery formed with two opposite tapered neck portions 760. The pivot groove 78 of each of the combination pieces 70 has a periphery formed with two opposite tapered lip portions 780.

As shown in FIGS. 4 and 5, the pivot shaft 76A of a first combination piece 70A is inserted into and pivotally mounted in the pivot groove 78 of an adjacent second combination piece 70, and a movable gap 79 is defined between each of the two opposite tapered neck portions 760A of the first combination piece 70A and the respective tapered lip portions 780 of the second combination piece 70, so that the first combination piece 70A and the second combination piece 70 are pivotable relative to each other. Thus, the combination pieces 70 are pivotable relative to each other.

When in use, the first combination piece 70A can be pivoted relative to the second combination piece 70 as shown in FIG. 6. Thus, when the shoe cushion 60 are subjected to bending force applied by the shoe sole 55 of the shoe body 50, the combination pieces 70 can be pivoted relative to each other so that the shape of the shoe cushion 60 is changed freely in one-dimensional direction so as to conform to the profile of the shoe sole 55 of the shoe body 50 and the profile of the user's foot, thereby providing a comfortable sensation to the user wearing the shoe.

Referring to FIG. 7, the shoe cushion 60 further comprises a plurality of secondary combination pieces 75 pivotally connected with each other. The secondary combination pieces 75 are juxtaposed to each other and arranged in a longitudinal manner. Preferably, the combination pieces 70 and the secondary combination pieces 75 are arranged in a staggered manner. Thus, the shape of the shoe cushion 60 is changed freely in two-dimensional direction so as to conform to the profile of the shoe sole 55 of the shoe body 50 and the profile of the user's foot, thereby providing a comfortable sensation to the user wearing the shoe.

Referring to FIG. 8, the combination pieces 70 of the shoe cushion 60 are integrally formed on the shoe sole 55 of the shoe body 50.

Accordingly, the combination pieces 70 can be pivoted relative to each other so that the shape of the shoe cushion 60 is changed freely so as to conform to the profile of the shoe sole 55 of the shoe body 50 and the profile of the user's one foot, thereby providing a comfortable sensation to. the user wearing the shoe. In addition, the shape of the shoe cushion 60 is changed freely in one-dimensional or two-dimensional direction, so that the shoe cushion 60 is bent freely to facilitate motion of the user's one foot.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
